Interface KieBase

All Superinterfaces:

KieBaseEventManager

public interface KieBase
extends KieBaseEventManager

The KieBase is a repository of all the application's knowledge definitions. It will contain rules, processes, functions, type models. The KieBase itself does not contain runtime data, instead sessions are created from the KieBase in which data can be inserted and process instances started.
